The Callisto Protocol
In this narrative-driven, third-person survival horror game set 300 years in the future, the player will take on the role of Jacob Lee – a victim of fate thrown into Black Iron Prison, a maximum-security penitentiary located on Jupiter's moon, Callisto. When inmates begin to transform into monstrous creatures, the prison is thrown into chaos.
What it feels like
The mutated creatures and chaotic prison present an active, present threat to the player throughout. The confined Black Iron Prison setting with its crushing atmosphere presses heavily on the experience. The transformation of inmates and slow-building tension of survival horror creates anticipatory fear.
What it's about
Set 300 years in the future on Jupiter's moon Callisto with futuristic technology and speculative setting. Enduring a hostile environment of mutated creatures and prison dangers is the central survival struggle. The game emphasizes uncovering dark secrets of the prison and the moon, suggesting hidden plots.
How it plays
Close-quarters combat with melee weapons and hand-to-hand fighting is a core interaction against mutated inmates. Firearms and ranged combat play a significant role in surviving encounters within the prison. Avoiding detection and strategically approaching enemies is a meaningful survival tactic within the horror setting.
How it looks and sounds
The entire game is designed as a third-person action-horror experience with the camera following Jacob Lee throughout the prison. The game features high-fidelity 3D graphics aiming for realistic visual rendering of the prison, creatures, and space setting. The grimy, worn industrial aesthetic of Black Iron Prison and the visceral transformations define the visual tone.
How it's structured
Designed exclusively as a single-player narrative experience. A bounded narrative arc with Jacob Lee's story arc from imprisonment to escape provides the story spine. The game is structured around progressing through the prison's linear spaces in a largely fixed order.
